What happens if the Camry RPM sensor breaks

1. Throttle position sensor.

Function: The throttle position sensor is to monitor the size of the throttle opening angle, determine the idle speed, full load and acceleration and deceleration conditions, and implement the throttle opening state.

Corresponding various injection volume control. Failure effects: Idle speed fluctuates high and low, or causes the phenomenon of speeding.

2. Intake valve pressure sensor.

Function: The intake pressure sensor is to provide engine load information, i.e. through.

In the case of pressure measurement on the air intake pipe, the air intake into the engine is indirectly measured, and then the air intake volume is converted into an electrical signal and provided to the computer through the internal circuit. Failure effect: causing the engine to be difficult to start, or idle unstable.

3. Inlet air temperature sensor.

Purpose: Provides air temperature information for correction of fuel injection and ignition timing. Failure effect: low idle speed, easy to stall.

4. Crankshaft angle sensor.

Function: It is to provide speed and crankshaft phase information, and provide reference points for fuel injection timing and ignition timing. Failure effects: The engine cannot be started or the engine suddenly stalls after starting.

5. Coolant temperature sensor.

Function: It monitors the engine coolant temperature and converts it into a voltage signal to the computer, and the ECU controls the amount of fuel injection, ignition timing and idle speed according to this signal. Effect of failure: Idling.

1. The indicator needle of the water temperature gauge does not move and points to the highest position; 2. It is difficult to start the cold car, because the water temperature sensor is faulty, and the temperature signal of the hot car is also displayed when the cold car starts, and the ECU can not get the signal of the over-concentrated mixture, so it can only provide the thinner mixture of the engine; 3. Fuel consumption increases, and the idle heading consumption speed is unstable; 4. It is difficult to accelerate, the accelerator is pressed to the end, and the engine speed cannot go up.

What does the water temperature gauge use to reflect the temperature of the engine coolant? It is through the water temperature sensor, also known as the water temperature sensing plug, usually the water temperature sensor is a negative temperature coefficient thermistor, which is installed in the engine cylinder head water jacket and is in direct contact with the cooling water, so as to measure the temperature of the engine cooling water. What are the signs of a failure if the water temperature sensor is broken?

The working principle of the water temperature sensor is to convert the cooling water temperature into an electrical signal, and correct the fuel injection amount, correct the ignition advance angle, and affect the idle control valve after the output of the electronic control unit

1. The indicator needle of the water temperature gauge does not move and points to the highest position;

2. It is difficult to start the cold car, because the water temperature sensor is faulty, and the temperature signal of the hot car is also displayed when the cold car starts, and the ECU can not get the signal of the over-concentrated mixture, so it can only provide the thinner mixture of the engine;

3. Fuel consumption increases, and the idle speed is unstable;

4. It is difficult to accelerate, the accelerator is pressed to the end, and the engine speed cannot go up.

In addition, the sensor is a kind of electronic component on the automobile circuit, if it is broken, there is basically no room for repair, only to replace it. So how can you tell if the water temperature sensor is broken? The simplest is to use a multimeter and then use a hair dryer to heat the water temperature sensor, if the resistance value does not change, then it means that this water temperature sensor is broken.

Secondly, it can be checked with a fault diagnosticator, but it should be noted that the inspection should be carried out when the car is cold.

The damage to the Camry's oxygen sensor affects the operation of the engine, resulting in a decrease in power and an increase in fuel consumption. The oxygen sensor is because once the air-fuel ratio of the mixture deviates from the theoretical air-fuel ratio, the purification ability of the three-way catalyst for CO, HC and NOx will decrease sharply, so the oxygen sensor is installed in the exhaust pipe to detect the concentration of oxygen in the exhaust gas, and send a feedback signal to the ECU, and then the ECU controls the increase or decrease of the fuel injection volume of the fuel injection finch device, so as to control the air-fuel ratio of the mixture near the theoretical value. Common faults of oxygen sensors are as follows:

1. Oxygen sensor poisoning: due to the excessively high exhaust temperature, the lead invades its interior, hinders the diffusion of oxygen ions, and makes the oxygen sensor fail, so it can only be replaced;

2. Carbon deposition: due to poor combustion of the engine, carbon deposition is formed on the surface of the oxygen sensor, and deposits such as oil or dust enter the lead removal or oxygen sensor, which will hinder or block the external air from entering the oxygen sensor, so that the signal output of the oxygen sensor is inaccurate, and the ECU cannot correct the air-fuel ratio in time;

3. Fragmentation of oxygen sensor ceramics: The ceramics of oxygen sensors are hard and brittle, and they may be broken and invalid when knocked with a hard object or blown with a strong air flow;

4. Early burnout of heater resistance wire pin bridge: For heating oxygen sensor, if the heater resistance wire is ablated, it is difficult to make the sensor reach the normal working temperature and lose its effect.

The speed sensor of the car is installed next to the output shaft of the gearbox, and one is also installed on the odometer for the auxiliary transmission. In the past, most of the vehicle speed sensors were linked to the propeller shaft and transmitted to the speedometer through the flexible shaft to display the corresponding speed, but now the electronic sensor is commonly used, which is installed in the same position, but no longer uses the flexible shaft, but uses a wire to transmit the speed signal to the speedometer.

The speed sensor is usually installed in the drive axle housing or transmission housing, and the vehicle speed sensor signal line is usually installed in the shielded jacket, which is to eliminate the electromagnetic and radio frequency interference generated by the high-voltage electric fire wire and the vehicle-mounted ** or other electronic equipment, and is used to ensure that electronic communication is not interrupted to prevent deterioration of driving performance or other problems. The following is a diagram of the installation location of the vehicle speed sensor.

Vehicle speed sensor installation locationThe speed sensor of the car is installed next to the output shaft of the gearbox, and one is also installed on the odometer for the auxiliary transmission, and the latter plays the role of failure protection after the former fails.

The function of the vehicle speed sensor.

1. Detect the driving speed of the car, and input the test results to the automobile instrument system to display the vehicle speed;

2. Input the vehicle speed signal of the detection junction to the ECU of the vehicle control system that requires the vehicle speed signal;

3. It is used for automatic transmission system and cruise control system.

<>Dear, if you look like our eighth-generation Camry, this oxygen sensor is generally not easy to damage, dear.

The signal of the oxygen sensor is offset, fixed and concentrated, and the circuit current is lower than the threshold value.

Long-term and short-term fuel corrections have not been looked at.

The data stream reads it.

It's no problem, it's just that the fault light is cleared and turned on again after running dozens of kilometers, and the gasoline has been changed to 95.

The oxygen sensor is broken.

Change. Put the oxygen sensor.

Remove it and wash it.

After washing, it doesn't work, you said that the oxygen sensor in the front or the back is broken.

You have to look at the fault code.

Let's take a look at which oxygen sensor this is in.

Which one is reported is that the sensor is broken.

Is this car a six-cylinder?

If you have a six-cylinder, it's this 135

135 measurements of this rear oxygen sensor.

The Camry has 6 cylinders of 4 cylinders.

In the case of four cylinders, this one must be a rear.

Back. Post-oxygen.

This code must be broken by the oxygen sensor?

That's right. Or three-way catalytic blockage.
